Abstract
A lifting hook balancing pulley assembly for large-tonnage hoist is composed of a balancing box, two transverse pulleys installed to bottom of said balancing box, two longitudinal pulleys and their connecting plate, longitudinal pulley swinging axle linked with said connecting plate, pin axle, steel cables for said pulleys, and lifting hook.
Description
(1) technical field
The present invention relates to large tonnage crane hook balancing assembly pulley.
(2) background technology
World shipping cause fast development at present, boats and ships carrying tonnage continues to increase, and shipbuilding is also increasing with crane thereupon, the ambassador's Current Collector Sleave that adds of suspension hook increases, make troubles so just for the lifting transportation, domestic most units adopt balance beam type suspender, overcome the stressed unbalanced problem of rigging.But it is less that this scheme is regulated the rigging scope, and strained condition is bad, and the degree of utilization of rigging is not high.
(3) summary of the invention
The technical problem to be solved in the present invention provides a kind of strained condition that had both changed each hoist cable, overcomes the contradiction of discontinuity equalization again, and has strengthened rigging and regulated the large tonnage crane hook balancing assembly pulley of surplus.
The technical scheme that adopts is:
Large tonnage crane hook balancing assembly pulley comprises balance box, horizontal pulley, vertical pulley, vertical pulley connecting panel, vertical pulley oscillating axle, bearing pin.Described horizontal pulley is two, and two horizontal pulleys and sheave shaft are contained in two ends below the balance box respectively.Described vertical pulley is two, and vertically pulley is contained on vertical pulley connecting panel with its sheave shaft, and vertically the pulley connecting panel is connected with vertical pulley oscillating axle, in the middle part of two vertical pulleys are contained in below the balance box by two vertical pulley oscillating axles respectively.All be wound with rope rig on two horizontal pulleys and two vertical pulleys, balance box is connected by bearing pin on the suspension hook group of crane, constitutes large tonnage crane hook balancing assembly pulley.
Above-mentioned vertical pulley can be around vertical pulley oscillating axle swing, and its pivot angle is 15 ° to the maximum.
Advantage of the present invention is: select for use the fixed length rigging can realize that on a large scale random length regulates, though by the physical dimension of lifting object how, the weight size, can both regulated at will to the rigging stress equalization, easy to use, also improved the degree of utilization and the operating efficiency of rigging.
(4) description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
Fig. 4 is the pulley lifting scheme drawing of two groups of different directions in length and breadth.
Fig. 5 selects horizontal one group of pulley or vertical one group of pulley lifting scheme drawing for use for irregular object.
Fig. 6 is with equalizer pulley upset object scheme drawing.
(5) specific embodiment
Large tonnage crane hook balancing assembly pulley comprises balance box 1, horizontal pulley 2, vertical pulley 3, vertical pulley connecting panel 8, vertical pulley oscillating axle 5, bearing pin 7.Described horizontal pulley 2 is two, and two horizontal pulleys 2 are contained in balance box 1 following two ends respectively with its sheave shaft 6.Described vertical pulley 3 is two, vertically pulley 3 is contained on vertical pulley connecting panel 8 with its sheave shaft 9, vertically pulley connecting panel 8 is connected with vertical pulley oscillating axle 5, two vertical pulleys 3 are contained in balance box 1 following middle part by two vertical pulley oscillating axles 5 respectively, vertically pulley 3 can be around vertical pulley oscillating axle 5 swings, and its pivot angle is 15 ° to the maximum.All be wound with rope rig 4 on two horizontal pulleys 2 and two vertical pulleys 3, balance box 1 is connected by bearing pin 7 on the suspension hook group 10 of crane, constitutes large tonnage crane hook balancing assembly pulley.
Concrete working example is as follows:
1, the lifting visual appearance size of straight object with main and auxiliary hoist lifting hook equalizer pulley group, utilizes one group of horizontal pulley 2 or one group of vertical pulley 3 to finish the lifting (see figure 4).
2, the lifting of irregular object can be by oad, selects for use wherein one group of horizontal pulley 2 or one group of vertical pulley 3 to finish, and can not influence the Hoisting Program (see figure 5) because of the restriction of oad.
3, in hoisting process, assembly pulley can be regulated the length of rope rig 4 arbitrarily, makes the rigging stress equalization, particularly needs the object that stands up, compares with common equalizing bar rigging, and its advantage is more obvious, more can provide the operating efficiency (see figure 6).
